AS1851, NFPA10, etc establish maintenance intervals for portable fire extinguishers as (typically) one year. While some standards specify an annual hydrostatic test, gage verify, etc; none discuss the physical basis of this requirement.
Why not 9 months or 34 months? Is there any performance or reliability data for portable fire extinguishers that indicates 12 months provides an n-sigma margin or whatever? thanks, Brian - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
